“…In the present study, the optimum feeding rate for juvenile pompano was 8% body weight per day, since growth was lower in fish fed with 4% body weight per day, and feeding rate above 8% body weight per day did not improve growth. The optimal feeding rate found for juvenile pompano (8% body weight per day) was high when compared to those reported for others subtropical species, such as Sparus aurata (Mihelakakis et al, 2002), Paralichthys olivaceus (Kim et al, 2007), and Limanda ferruginea (Puvanendran et al, 2003), of 2.3, 2.6, and 3.0% body weight per day, respectively. The feeding rate of juvenile pompano seems to be closer to values found for tropical fish, including Clarias gariepinus (8% body weight per day) (Marimuthu et al, 2011) and Colossoma macropomum (10% body weight per day) (Silva et al, 2007), which is probably due to the high metabolism of T. marginatus (Cunha et al, 2009).…”

-The objective of this work was to evaluate the ideal feeding rate and frequency for juvenile pompano (Trachinotus marginatus). Two experiments were carried out in a completely randomized design, with three replicates each. In experiment I, 25 fish (4.8±0.6 g and 6.48±0.01 cm) were stocked in 15 tanks (50 L) during 21 days and fed 4, 8, 12, 16, and 20% body weight per day. In experiment II, 20 fish (4.1±0.1 g and 6.6±0.1 cm) were stocked in 15 tanks (40 L) during 28 days and fed 2, 6, 8, and 10 times a day. The tested feeding rates and frequencies did not influence survival. Final weight and length in experiment I were significantly lower in fish fed 4% body weight per day, whereas in experiment II only weight was significantly lower in fish fed 2 and 6 times a day. At the end of both experiments, apparent feed conversion showed significant difference, with the worst value observed for fish fed 20% body weight per day in experiment I and 2 times a day in experiment II. Juvenile pompano show better growth performance when fed 8% body weight per day and 8 times a day.Index terms: Trachinotus marginatus, feed management, marine fish culture. Taxa e frequência alimentar no crescimento de juvenis de pampoResumo -O objetivo deste trabalho foi avaliar a taxa e a frequência alimentar ideal para juvenis de pampo (Trachinotus marginatus). Foram conduzidos dois experimentos, em delineamento inteiramente casualizado, com três repetições cada um. No experimento I, 25 peixes (4,8±0,6 g e 6,48±0,01 cm) foram estocados em 15 tanques (50 L) durante 21 dias e alimentados com 4, 8, 12, 16 e 20% da biomassa total por dia. No experimento II, 20 peixes (4,1±0,1 g e 6,6±0,1 cm) foram estocados em 15 tanques (40 L) durante 28 dias e alimentados 2, 6, 8 e 10 vezes por dia. As taxas e as frequências alimentares testadas não influenciaram a sobrevivência. O peso e o comprimento finais no experimento I foram significativamente menores nos peixes alimentados com 4% da biomassa total por dia, enquanto, no experimento II, somente o peso foi significativamente menor nos peixes alimentados 2 e 6 vezes por dia. Ao final dos dois experimentos, a conversão alimentar aparente apresentou diferença significativa, com pior valor observado nos peixes alimentados com 20% da biomassa total por dia, no experimento I, e 2 vezes por dia no experimento II. Juvenis de pampo apresentam melhor desempenho de crescimento quando alimentados com 8% da biomassa total por dia e oito vezes por dia.Termos para indexação: Trachinotus marginatus, manejo alimentar, piscicultura marinha.

“…Studies have shown that a suitable feeding rate and frequency improve growth and feed conversion (Wang et al, 1998;Van Ham et al, 2003;Cho et al, 2007), reduce variation in fish size within groups (Jobling, 1994), and minimize feed wastage and water pollution (Puvanendran et al, 2003).…”

“…; valor abaixo da taxa utilizada por esta espécie para máximo crescimento (3%) (PUVANENDRAN et al, 2003). Nas condições deste estudo, embora a taxa de 1% do peso vivo/dia apresente a melhor conversão alimentar para tambaquis criados em tanque-rede, o ganho de peso e a produção ficaram abaixo dos obtidos na taxa de 3%, que seria a taxa adequada para alcançar o crescimento ótimo em viveiros (MELO et al, 2001).…”

“…Identifying R opt enables producers to grow healthy fish as quickly and/or efficiently as desired and using an R opt avoids overfeeding, which is costly and reduces water quality (Sumagaysay, 1998;Puvanendran et al, 2003). In this study, we use a range of daily…”
